Learning outcomes
• Today we will cover…
• Why smoke control is important
• Overview of Smoke Control Dampers (compared to fire dampers)
• Smoke Control Damper classifications
• Look at strategies and best practice
Key fire and smoke terminology
• Compartmentation is…
• Keeping the fire and smoke limited to one part of a building
• Cause and effect is…
• Which dampers open
• Which dampers close
• Some of these dampers will be fire dampers, some smoke dampers
• Details hot/cold smoke extraction
• The wider cause and effect may include AOVs, fans and fire doors
Why Smoke Control?
Our industry understands better than most that it is not the fire that kills, but smoke.
• Grenfell Tower - shock waves through the building services industry.
• Under the radar … until disaster
…Smoke is the #1 Killer in UK Fires.

The drive towards compliance….
• Product Standard BS EN12101-8
• Classification Standard BS EN13501-4
• Test Standard BS EN1366-10
• First published April 2011
• Widely used in Europe for smoke control
• UK had previously favoured fail-safe closed actuators, part 10 uses drive open/drive closed.
• Post-Grenfell fire, industry re-focusing on standards and applications.
Fire Dampers (MSFD or FD)
Fire damper function is to maintain compartmentation
• Fire dampers to be CE marked to BS EN 15650
• Tested to BS EN 1366-2
• Classified to BS EN 13501-3
Fire Dampers
✓ have thermal release mechanism at 72*C
✓ fail safe-close
✓ have fire resistance in closed position
✓ have known leakage characteristics (determining classification ‘E’ or ‘ES’)
Smoke Control Dampers (MSD)
Smoke control damper function is to contain/maintain an extraction path for smoke.
• The CE marked to BS EN 12101-8
• Tested to BS EN 1366-2 and BS EN1366-10
• Classified to BS EN 13501-4
Smoke control dampers:
✓Drive to open or closed position < 60 seconds
✓Maintain their position – non-fail safe
✓ Have known leakage characteristics
✓Maintain free area in open position at standard or elevated temperatures

We will now look at the last three parts of the classification in more detail!
Classification Breakdown
Hot 400/30
The test to achieve this part of the classification involves cycling the damper whilst the damper is under elevated temperature
• The test is 60 minutes long
• The damper is cycled every 150 seconds for the first 30 minutes rising from ambient to 400 degrees within 7 minutes.
• After 30 minutes the damper is to remains open for the duration of the test and the time temperature curve goes back to the standard time temperature curve. (38 minutes - 877°C, ending at 60 minutes - 945°C)
• Passing only the Hot400/30 test does NOT mean a damper is 1366-10
AA / MA
Typically we use AA dampers in the UK for cold smoke clearance…
• AA Smoke control system with automatic activation smoke control system (smoke and heat exhaust ventilation type or pressure differential type), that operates automatically on receipt of a smoke or fire alarm without any manual action/intervention NOTE systems with an attended control room classed as an automatic system.
• MA Smoke control system with manual intervention smoke control system (smoke and heat exhaust ventilation type or pressurization type), that will be put into manual operation, on detection smoke or fire. This is instigated with human intervention leading to a sequence of automatic actions.
• For most applications, we recommend using an AA system with dedicated damper control panel
Multi / Single
Single compartment smoke control damper :
“smoke control dampers for use in single
compartment areas, which may be associated with
smoke control duct tested according to EN1366-9
and/or may be installed in an external wall, floor or
roof [ceiling]“
Multi compartment fire resisting smoke control
damper: “smoke control dampers for use in multi
compartment areas, which may be associated with
smoke control duct tested according to EN1366-8
and/or may be installed within or on the face of a
fire compartment structure"

Cause and effect
• The building is divided into zones
Cause and effect
• These zones are normally then mapped into a spreadsheet –which is used by all parties to ensure a joined-up controls strategy across fire alarm, damper, AHU/extract fans and the BMS
• Used by panel manufacturer to add controls logic to the panel
Controls
• Life safety product, with a <10s reaction time
• Thermal protection of devices and networks is paramount in event of fire
• There are numerous devices involved in the actuation of dampers
• Damper
• SDI decoder interface
• Cabling
• Damper Control Panel
• Benefits of using a dedicated damper control panel manufacturer
• Capable of complex ‘Cause and Effect’
• Integration into BMS systems
• Scheduled damper testing and status alerts
BESA DW145 Guidelines
• Important aspects of FSD installations including
• Responsibility of all parties involved in the overall sequence from system specification through to compliant installation.
• Emphasis is placed on all parties to work as a team.
• DW145 indicates particular responsibilities that are allocated on a project specific basis.
RIBA Plan of Works Stages – how can we apply this to Smoke Control
RIBA Stage 2 -concept design
Building designed into
zones - engage specialist
manufacturer
RIBA Stage 3 -developed
design
Draft cause and effect
strategy for dampers
RIBA Stage 4 -Detailed design
Specify correct dampers
according to cause and
effect
RIBA Stage 5 –Construction
Engage with building
control and specialists on
site
RIBA Stage 6 -Handover
Utilise specialist
manufacturers to support
commissioning
Conclusion
• Design your cause and effect early to outline cause and effect –then specify dampers, controls and actuators accordingly
• Take note of the ductwork specification 1366-8
• Smoke control is about providing a path for extracting smoke
• Recommended you use a dedicated controls system
• Make sure you use Multi Compartment vs Single Compartment dampers correctly
• A joined up approach – start to finish – key to executing the strategy
